Observation of Replica Symmetry Breaking in Filamentation and Multifilamentation
André C. A. Siqueira, Guillermo Palacios, Jessica E. Q. Bautista +4
We report the experimental observation and characterization of Replica Symmetry Breaking (RSB) manifestation while analyzing the transverse intensity profile of pulses in filamenta…
Multiple Temporal Compression as a method to control the generation of bright and dark solitons
André C. A. Siqueira, Palacios G., Mario B. Monteiro +4
Recently published works have shown that the Multiple Temporal Compression (MTC) method is a more efficient approach for generation of multiple bright solitons in stacked waveguide…
Generation of robust temporal soliton trains by the multiple-temporal-compression (MTC) method
André C. A. Siqueira, Guillermo Palacios, Albert S. Reyna +3
We report results of systematic numerical analysis for multiple soliton generation by means of the recently reported multiple temporal compression (MTC) method, and compare its eff…
Generation of multiple ultrashort solitons in a third-order nonlinear composite medium with self-focusing and self-defocusing nonlinearities
André C. A Siqueira, Edilson L. Falcão-Filho, Boris A. Malomed +1
Theoretical consideration of the propagation of femtosecond-Gaussian pulses in a 1D composite medium, consisting of alternating self-focusing (SF) and self-defocusing (SDF) wavegui…
Observation and analysis of creation, decay, and regeneration of annular soliton clusters in a lossy cubic-quintic optical medium
Albert S. Reyna, Henrique T. M. C. M. Baltar, Emeric Bergmann +5
We observe and analyze formation, decay, and subsequent regeneration of ring-shaped clusters of (2+1)-dimensional spatial solitons (filaments) in a medium with the cubic-quintic (f…
Optical vortices: the concept of topological potential and analogies with two-dimensional electrostatics
Anderson M. Amaral, Edilson L. Falcão-Filho, Cid B. de Araújo
We show how the phase profile of a distribution of topological charges (TC) of an optical vortex (OV) can be described by a potential analogous to the Coulomb's potential for a dis…
Distinguishing orbital angular momenta and topological charge in optical vortex beams
Anderson M. Amaral, Edilson L. Falcão-Filho, Cid B. de Araújo
In this work we discuss how the classical orbital angular momentum (OAM) and topological charge (TC) of optical beams with arbitrary spatial phase profiles are related to the local…
